Tuesday Forecast

DAYS 1-5 (DECEMBER 11-15)
Broad low pressure offshore and high pressure to the north will combine to keep it cold and becoming a little more blustery through Wednesday along with the risk of some ocean-effect snow showers favoring Cape Cod. A disturbance from the west will enhance cloudiness and add some instability for snow shower development a little closer to the rest of the Massachusetts eastern coast tonight into Wednesday. Although high pressure takes more control as it sinks southward from eastern Canada Thursday, the remains of a disturbance from the west may bring some cloudiness in at times but no threat of precipitation. By Friday the high will shift offshore and low pressure approaches from the west, bringing a modest warm-up and a chance of rain Friday night into the start of the weekend.
Forecast details…
TODAY: Sunny except partly sunny Cape Cod and at times to the eastern MA coast. Highs 27-33. Wind N up to 10 MPH.
TONIGHT: Partly to mostly cloudy. East coastal snow flurries possible. Lows 18-24. Wind NE up to 10 MPH.
WEDNESDAY: Mostly cloudy to partly sunny. Possible snow showers east coastal areas, favoring MA South Shore and Cape Cod where minor accumulation may occur. Highs 28-35. Wind NE 5-15 MPH.
WEDNESDAY NIGHT: Variably cloudy. Lows 12-18. Wind light N.
THURSDAY: Partly sunny. Highs 28-35. Wind light variable.
FRIDAY: Mostly cloudy. Chance of rain at night. Lows in the 20s. Highs in the 40s.
SATURDAY: Cloudy. Periods of rain. Temperatures steady in the 40s.

DAYS 6-10 (DECEMBER 16-20)
Low pressure will continue to influence the weather December 16-17 but most of it shifting south and east of the region with some rain/snow showers possible, becoming breezy, and somewhat colder. Fair, chilly December 18. Slightly milder and watching a disturbance of some kind for a rain/snow shower risk later in the period.

DAYS 11-15 (DECEMBER 21-25)
This period will neither feature a big warm up nor major cold, but temperatures likely starting milder than normal then trending toward normal. Odds are against pre-Christmas snowfall, but a couple minor systems may deliver rain and/or snow showers.

    1. I bet it’s beautiful in NC and VA with their deep snow cover. I’ll check with my relatives there at some point later. 🙂

      1. Why is it embarrassing? It’s just weather. 🙂 This is not the first time and it is far from the last that we’ll have an odd snowfall distribution early in the season. With Logan surrounded by warm water when that November storm happened, it makes perfect sense.

  11. Mark,

    Do you have any snow maps from the Euro. I had to cancel my service, so all I can
    see are the silly maps from Tropical tid bits, which are mostly useless. thanks

      1. No, the low tracks well out to sea and the precip shield stays off shore with the northern fringe maybe 50-75 miles south of Nantucket.

        The Euro does look like it is trying to conjure something up at hour 240 (12/21). Clipper diving down from Canada with some troughing in the northeast and some coastal redevelopment. Might end up too late (and too warm) for us though.

  14. Some where from the 20th on through the 28 period, I feel like we get winter weather some where in SNE. Look for a storm to pop up on the models around within 4 days before the day it happens.

  15. CPC pulled a 180, having been insisting on above normal precip in the 6-10 and 8-15 the last few days, only to change the 6-10 (a period they had been forecasting wet) to below normal today. They should be backing off a tad on the magnitude of their mild forecast as well.

    1. They were never above climatology and they are probably near or slightly below climatology at the moment.

      People are reading too much into the medium range models, however, that I have warned will be very erratic for some time. That time continues.

  18. I thought, perhaps, I might find a few flurries on my car top this morning, as it seems there were some radar echoes over Marshfield last night, but no. We’ll keep an eye out if we get brushed by any ocean effect activity today.
